Folding seat-bed frame

Abstract

A frame member supports a seat and a back and is movable between a horizontal position for supporting a user thereon and a vertical position for stowing the frame against the wall. Linkage secures the frame member to a wall mounting apparatus. The linkage includes oppositely disposed pairs of links that pivot the frame member relative to the wall to define a first distance between the wall and the frame member when the frame is in the vertical position and a second lesser distance between the wall and the frame member when the frame is in the horizontal position thus requiring less space between the frame and the wall. The frame assembly also has a leg pivotally connected to the frame member by linkage such that the leg moves beneath the frame between an upstanding supporting position and a collapsed storage position coincident with movement of the frame.

1. A seat-bed frame for connecting to a wall so that a seat-bed is movable between a generally horizontal position for supporting a user thereon and a generally vertical position for stowing said seat-bed along the surface of the wall when the seat-bed defines a bed, said frame comprising:
 a frame member for supporting said seat-bed; 
 a wall mounting apparatus for securing said frame member to the wall; and 
 linkage connecting said wall mounting apparatus and said frame member to define a first distance between said wall and said frame member when said seat-bed is in said vertical position and a second distance between said wall and said frame member when said seat-bed is in said horizontal position, said second distance being less than said first distance, said linkage including oppositely disposed pairs of links between said wall mounting apparatus and said frame member, each pair of links including an outside link with one end pivotally attached to an outside surface of the wall mounting apparatus and its other end pivotally attached to an outside surface of the frame member, and an inside link with one end pivotally attached to an inside surface of the wall mounting apparatus and its other end pivotally attached to an inside surface of the frame member, wherein the links move such that said outside link is transverse to the wall to which the seat-bed is connected when said seat-bed is in said vertical position, said inside link is parallel to the wall when the seat-bed is in said horizontal position. 
 
     
     
       2. A frame assembly according to  claim 1 , wherein said frame member is movable so as to define (i) a seat with a back or (ii) a bed.
